S'AWlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 393,371, dated November 27, 1888.

Application filed July 11, 1888. Serial No. 279,656. (No model.) I

To aZZ zghom it may concern.-

Be it known that I, GEORGE A. JACKSON, a citizen of the United States, residing at Sec-- 0nd Creek, in the county of Greenbrier and State of West Virginia, have invented a new and useful Improvement in Sawing-Machines, of which the following is a specification.

My invention relates to an improvement in sawing-machines; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of my improved sawingmachine, showing the same arranged in position for sawing fallen logs. Fig. 2 is a similar view showing my improved sawing-machine attached to a saw-horse and adapted for sawing fire-wood. Fig. 3 is a detail View.

A represents a supportingstandard, which is provided at its lower end with an engagingpoint, B, and has a notch or recess, 0, at a suitable distance from itslower end. Attached to the standard A at a suitable distance from its lower end is a hook-rod, D, having an engaging-point.

E represents an A-shaped frame,which comprises a pair of inclined bars, F, having their upper ends bolted together, and a crossbar, G, which connects said bars F at a suitable distance from theirlower ends. The ends of the crossbar G project beyond the bars F for a suitable distance.

H represents a pair of vertical arms, which are attached at their central portions to the lower ends of the bars F, and are also secured near their upper ends to the ends of the bar G. To the lower ends of the arms H are secured right-angled irons I, the lower portions of which form horizontal studs that project beyond the outer sides of the arms, and the upper ends of the said arms are fashioned into handles.

K represents a rectangular link, which is arranged between the upper end of the frame and the standard A, and a bolt, L, extends transversely through the upper end of the frame E, standard A, and through the link K, said bolt thereby connecting said frame, link, and standard together and adapting the frame to swing or oscillate, as will be readily understood.

M represents a catch or yoke, which is pivoted to the center of the bar Gand has a hook at its free end adapted to engage the recess 0 and thereby secure the swinging frame firmly to the standard A when the sawingmachine is not in use.

On the outer side of the standard A is arranged brace rod N, which is provided with a longitudinal slot at its upper end.

0 represents a bolt, which projects from the standard A and engages the said slot, and has a clamping-nut, P, by means of which the brace N may be secured to the standard at any desired longitudinal adjustment. The said .brace is provided at a suitable distance from its rear end with a pivoted engaging-hook arm, It.

S represents a crosscutsaw of the usual construction, to the ends of which on one side are secured blocks T, the same being provided on their innersides at their inner ends with recesses U, and having inwardly-extending arms V. The lower ends of the arms H are inserted in the recesses U, and the outwardlyextending studs at the lower end of the anglearms I bear under the projecting armsV and thereby secure the saw to the swinging frame and permit the saw to be adjusted vertically on the parallel arms H.

The operation of my invention is as follows: In order to saw a fallen log, the standard A has its pointed lower end secured to the ground on one side of the log. The hook arm D of the said standard is driven into thelog. The brace N is inclined at a suitable angle and caused to bear against the opposite side of the log, and the hook-arm It thereof is driven into the log, thereby firmly securing the standards and the brace-arm thereto. The frame E, being free to swing or oscillate from the upper end of the standard, the operator, stationed on one side of the log, grasps the handle at the upper end of one of the arms H and swings the frame, thereby causing the saw to move backward and forward over the log. As the saw cuts into the log it slides downward on the arms H by its own gravity, and is thus fed automatically to its work.

In order to saw moved from the standard A, and the latter has its lower end bolted to one side of a saw-horse, a, as illustrated in Fig.2, the saw being there- IOO/ fire-wood the brace N is re- 2. The combination oi the vertieai standard A, the hook D,pivoted thereto, the slotted arm N, having the hook R, and the clamping-bolt extending through the standard and the slot of the arm, with the swinging saw-frame pivoted to the standard, substantially as described.

In testimony that I eiai m the foregoing as my own I have hereto afiixed my signaturein presenee of two witnesses.

by arranged in position to out a log arranged on the saw-horse and projecting from one side thereof, as will be readily understood.

Having thus described my invention, I i

1. The combination oi the vertical standard A, the swinging frame E, pivoted to the upper end thereof, said frame having the inclined bars F, the cross-bar G, connecting them, and the vertical bars II, secured to the lower ends of bars 1* and to the ends of bar G and having handles at their upper ends, and the l saw-blade having the blocks T at its ends, engaging and adapted to slide vertically on the 1 bars II, substantially as described.
